I have a 1986 V16o Ray Craft with a 1975 115 HP Johnson. This motor has a 13.3/8x17 prop. Like to get a new one in the future and I'm trying to figure out which one. One salesman said a 13.25x17 4 blade. Run prop check on computer and it said for water sports and heavy loads a 13.25x21 3 blade are a 13x21 4 blade. For cruising and speed a 13.25x23 3 blade are 13.23 4 blade. Like to know What was on this boat when sold new.
